HINGE.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed October 12, 1915. Serial No. 55,570.

the loose pin hinge and the spring pressed hinge and which is soconstructed that the .loose pin may be removed and replaced and the leafmembers of the hinge separated without demounting the spring element orits connections.

Another object is to provide means for retaining the spring element onone of the leaf members against displacement but which permits of thespring being ad usted to vary its tension and also permits of its readyremoval for renewal or repairs.

Another object is to provide a construction in a hinge of the abovecharacter wherein the ordinary loose pin. may be employed and in whichthe pin may be disposed in the hinge from either end thereof so that thehinge may be set in position and employed with either end up.

Another object is to provide means for engaging the opposite ends of thespring element to hold it independent of the removable pin by which oneend of the spring is detachably held in fixed relation to the hinge leafon which it is carried and the other end vadjustably connected to theother leaf member.

Another object is to provide a spring hinge for normally maintaining theclosure to which it is attached in a closed position and in which theleaf members of the hinge may be readily separated and reconnected .inremoving and replacing the closure.

A further object is to provide a removable pin spring hinge which issimple in construction and is composed of few parts, so

formed and arranged as to be readily constructed and assembled.

The invention is illustrated in the accent panying drawings in which:

Figure l is a view in perspective illustrating the hinge as applied to adoor and its casing.

Fig. 2 is a view of the hinge as disposed in an open position showing itpartly in vertical section and partly in elevation.

Fig. 3 is a view in horizontal section on the line 3-3 of Fig. 1 showingthe hinge leaf members as positioned at right angles to each other.

Fig. 4: is a view in enlarged horizontal section on the line 4.& of Fig.2.

Fig. 5 is a view in enlarged horizontal section on the line 55 of Fig.2.

Fig. 6 is a perspective View of the demountable spring retaining shoe.

Fig. 7 is a view in horizontal section on the line 7-7 of Fig. 2illustrating the manner of mounting the spring adjusting sleeve.

More specifically, 10 and 11 indicate the leaf members of the hingewhich are formed with the usual screw holes and are adapted to beattached to a closure and its casing in the ordinary manner. is formedwith a tubular cylindrical spring receiving casing 12 which projectsfrom the inner vertical edge of the leaf member and has its endsterminating in spaced relation to the ends of the leaf member. The

cylindrical casing 12 is formed with an open upper end and has aninwardly proecting annular flange 13 on its lower end encircllng acentral opening 14 through which a loose pin 15 of the hinge is adaptedto extend.

Revolubly mounted on the open end of the cylinder 12 is a springadjusting sleeve 16 having an annular shoulder 17 interme' diate itsends adapted to seat on the open end of the cylinder 12. The sleeve 16is cylindrical in form and has portions 18 as to slidably fit the innerwall of the cylin der 12 and is formed with a continuous oir=cumferentially extending channel 20 adapt-- opening in the wall of thecylinder 12 by means of which the sleeve 16 is held against withdrawalfrom the cylinder but retained in revoluble relation thereto. The sleeve16 is formed with a central bore 22 arranged opposite the opening 14 andadapted to receive the pin 15.

A helical spring is disposed in the cylinder and has one end engaged bythe sleeve 10 and its opposite end engaged by an annular retaining shoe24:. arranged to seat on the flange 13 and encircle the pivot pin. As ameans for holding the shoe Ell. against rotation and at the same timepermit of its ready withdrawal and replacement, the shoe is formed witha cut away portion to provide a flat face or shoulder 25 at one sidethereof which is adapted to slidably engage a flat shoulder or face 26on a projection formed at the intersection of the inner face of theflange 13 with the inner wall of the cylinder. The engaging faces and 26serve as a pin and socket connection or key to hold the retaining shoeagainst rotation in the casing and permit of winding or unwinding of thespring 3 by rotation of the sleeve 16 in adjusting the tension of thespring and furthermore form a readily de tachable connection between oneend of the spring and the leaf member 10.

T he leaf member 11 is formed with a pair of spaced lugs 27 and 28 onone edge thereof which are adapted to be arranged with one of the lugsabutting against the flanged end of the cylinder and the other lugabutting against the outer face of the sleeve 16. The lugs 27 and 28 areformed with central bores and 30 extending therethrough which bores arearranged to aline with the opening 14: and the bore 22 and are pro videdfor the reception of the pivot pin 15. T he pivot pin 15 is of suchlength that when placed inv position it will extend, through one of thelugs 27 or 28 and project through the sleeve 16 and cylinder 12 into theother lug and may be placed in position from either end of the hinge sothat the hinge may be employed either end up. A head 31 is formed on thepivot pin 15 which seats on the lug and as a means for finishing theopposite end of the hinge, a knob is pro: rided which is fitted with athreaded stem adapted to be screwed into the bores or 30: these boresbeing internally threaded for a short distance adjacent their outer endsfor the reception of the stem In assembling the hinge the spring 23 isconnected to the sleeve 16 and the retaining n1 shoe 24- and is placedin position within the cylinder with the face of the shoe engagingthe-shoulder 26 of the cylinder. The set screw :21 is then screwed intoengagement with the annular channel 20 of the sleeve 16, thus holdingthe latter against withdrawal from the cylinder and at the same timecooperating with the spring to hold the retaining shoe in place; thespring 2 being under end-wise compression to exert a pressure on theshoe 2st when disp .sed in the cylinder with the sleeve secured inplace. The spring retaining shoe and the spring adjusting sleeve willthus be carried by the leaf member 10 with the spring and shoe incasedin the cylinder. The leaf member 11 is then disposed with the lugs 27and 28 arranged at the opposite ends of the cylinder whereupon the pivotpin 15 is introduced through one of the lugs and through the cylinderinto engagement with the other lug; the loose pin sliding into position.The knob 32 is then mounted on the opposite lug to complete the finishof the hinge.

To tension the spring 23 the sleeve 16 is rotated to contract the coilsof the spring by turning it in the direct-ion indicated by the arrow (4-in Fig. 3. A removablepin Set is then inserted in one of a series ofperforations formed in the periphery of the sleeve portion 19 so as toproject outwardly and engage the rear face of the leaf member 11. Thespring :23 will then operate to exerta pressure tending to close theleaf members 10 and 11 toward each other in the direction indicated bythe arrow 7) in Fig. The pin serves to prevent unwinding of the springand at the same time provides a connection between one end of the springand the leaf member 11.

ll hen it is desired to separate the leaf members of the hinge as inremoving the closure from its casing, the pin is first removed to relaxthe spring 23 whereupon the pivot pin. 15 is withdrawn. therebypermit-ting a separation of the hinge leaf members in the manner commonin the ordinary loose pin butt hinge.

An important feature of this invention resides in the manner in whichthe spring is retained in its casing against displacement but subject toadjustment and to ready removal and replacement.

ll hile l have specifically set forth the construction of the hinge asillustrated in the drawings. it is manifest that various changes may bemade in its detail construction without departing from the spirit andscope of the invention as set forth in the appended claim.

What I claim is:

In a spring hinge, a. leaf member, a t-ubusleeve against withdrawal fromthe casing the inner wall of the casing engageable but permitting itsrotation in relation therewith the flat face of the retaining shoe toto, a helical spring within the casing having hold the latter" againstrotation. 10 one end attached to said sleeve, a retaining In testimonywhereof I have signed my 5 shoe arranged within the casing with whichname to this specification.

the other end of the spring is engaged formed with a flat face, and aprojection on ABNER J. WINDER.
